Seachem Reef Carbonate offers a highly concentrated solution (4,000 meq/L) expertly crafted with a blend of carbonate and bicarbonate salts. This formulation is designed to restore and maintain alkalinity in reef aquariums, essential for optimal coral growth. By providing the necessary carbonates, Seachem Reef Carbonate ensures that coral health remains vibrant, aiding in preventing the decline that occurs when either calcium or carbonates become deficient.

The advanced formulation prevents depletion of calcium, magnesium, and strontium, common issues when alkalinity levels rise. Maintaining reef alkalinity between 3–5 meq/L (8–14 dKH) ensures a healthy environment for all reef inhabitants. The unique combination of salts yields a higher pK of roughly 9.0 in saltwater, offering enhanced pH stabilization around 8.3-8.4, unlike standard sodium bicarbonate solutions.

Seachem Reef Carbonate is easy to use at various experience levels. Beginners and experts alike can benefit from its precise dosing guidelines, ensuring a tailored approach to maintaining an optimal reef ecosystem. Through correct usage, reef keepers can preemptively combat issues associated with fluctuating pH levels and deficient alkalinity.
